Crash when opening a project when another project is already open

1. Start in debug mode, open the attached project. TutorialProject.zip
2. Click on the 5th photo in the thumbnail list ("Pyrrhocoris1.tif") to make it the active photo.
3. Try to open the following project: TextureTestingSynth.zip The program crashes, apparently trying to access a photo from the first project. (Not sure what would happen if the 2nd project did contain a photo with that name.)

Current photo is now Pyrrhocoris1.tif
Traceback (most recent call last):

Similar thing also happens when creating a new project while another project is already open.
